【摘要】 将圆柱体岩石试件放在一对自制的半圆形钢制卡环内，进行变角板试验，并将其结果与标准正方体试件的试验结果进行比较，发现两种不同形状岩样的内聚力ｃ值及内摩擦角φ值比较接近，且圆柱体试件试验所得剪应力τ与正应力σ之间的相关系数大于０９６，破坏面理想，破裂体两半基本对称，故圆柱体试件变角板试验结果具有一定的可靠程度。更多还原

【Abstract】 Cylindrical rock samples are placed in a couple of semi-circle steel hoop Angle-varied plate experiments are carried Result from it is compared with that from the experiment of standard cubic samples It is found that cohesions c and interal frition angles φ of two sorts of rock samples are closer The relationship coefficient of τ and σ cylinder samples is more than 0 96 Split face is regular Two parts of sample are symmetric Thus, angle-varied plate experiment of cylinder rock samples is reliable更多还原
